microelectrode array

A microelectrode array is a device made up of many tiny electrodes, which are small conductors that can detect electrical signals. These electrodes are often used in neuroscience to study brain activity by recording signals from neurons (brain cells) or stimulating them. By placing the array on or near brain tissue, researchers can gather detailed information about how neurons communicate and respond to stimuli. This technology has applications in brain research, medical diagnostics, and even in developing brain-computer interfaces, which can help people control devices using their thoughts.
